WHEELER H. VIBBER, OF LONDON, CONNECTICUT, ASSIGNOR OF ONE-HALF TO THE GILLETTE VIBBER CO., OF NEW LONDON, CONNECTICUT, A CORPORATION.

CONDUIT CAP.

Application filed October 25,

To all whom t may concern:

Be it known that I, VHEELER H. Vrnnnn, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Conduit Caps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a view in side elevation of one from which my improved conduit-cap may assume.

Fig. 2 a View thereof in front elevation.

Fig. 3 a view thereof in vertical central section.

Fig. 4 a plan view thereof, showing, in broken lines, the cap as swung to one side.

Fig. 5 a view in side elevation of a modilied form of my improvement.

Fig. 6 a similar view of another modified form thereof.

My invention relates to an improved conduit-cap, the. object` being to provide the same with a splicing-chamber and thus furnish means for coupling the house and service wires at the cap, which is located outside of a building, instead of at the meter inside the building, whereby the cost of installation is properly divided between the house owner and the service company and confusion of accounts and responsibilities avoided.

With these ends in View, my invention consists in certain details of construction as will be hereinafter described and pointed out in the claim.

In carrying out my invention, as herein shown, I employ a conduit-cap of any approved construction, provided with a splicing-chamber also of any approved construction, so long as it is adapted to receive an ordinary conduit-pipe.. As shown in Figs. 1 to 4 inclusive, the said cap and splicingchamber are made independently of each other, and swiveled together, the former comprising a sheet-metal hood 10, and a base-plate 11 mounting two porcelain clamping or gripping members 12 traversed by kscrews 13, which also secure the hood 10 and the clamping-members 12 to the base-plate 11. The inner edges of the clamping-inem- 1922. Serial No. 596,789.

bers 12 are serrated, or otherwise roughened, to adapt them to firmly grip the service cable 14, or one or more service wires, as the case may be.

The splicing-chamber, which is interposed between the said cap and the conduitpipe, consists of a forwardly-opening castmetal body 15 provided at its lower end with a threaded socket 1G for the reception of the threaded upper end of an ordinary conduit-pipe 17 and closed in front by a U-shaped sheet-metal cover 18 secured in place by screws 19. As shown in Figs. 1 to 4 inclusive, the cap, which has bearing directly upon the top of the splicing-chamber, is swiveled thereto by means of a sleeve 2O having its upper and lower ends expanded and providing not only for the swiveling of the cap upon the splicing-chamber, but also for the passage of the cable 14 from the former down into the latter, in which its conductors 21 :21 are stripped for being spliced to the conductors 22:22 of the house cable 23, the upper end of which projects from the said conduit-pipe 17 into the lower portion of the splicing-chamber. The construction described would also serve equally well in case the wires were not wrapped together in cable foi-1n. By swiveling the cap upon the splicing-chamber, the` former is allowed to turn thereupon, as shown in Fig. 4, to accommodate itself to the direction from which the service wires approach the conduit-pipe.

In the modified construction shown by Fig. 5, the cap and splicing-chamber correspond to the parts already described, but the splicing-chamber is provided in its rear wall with a threaded opening 24 for the reception of the conduit-pipe 17, in this case horizontally-arranged, rather than vertically.

In the modified construction shown by Fig. 6, the conduit-cap 25 and splicingchamber 26 are made integral wit-h each other for installations which do not require Athe swiveling of the cap.

Under my invention, thc house-wiring is at the time of installation carried through the conduit-pipe to the splicing-chamber into which the service wires are, at any subsequent time, led for being spliced to the house wires. lVith my improved conduitcap, the line between the householder and his electrician and the service company is clearly defined.

screws passing through the said hood, grip- 10 ping-members and base-plate, whereby the said hood and members are secured to the said plate and the members .gripped upon theY cable.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
